A friend of mine asked the following question:
"When the Maryland Midland started running their Union Bridge-Highfield excursions 1984 or so, they had a former DT&I business car. Was this car, dark green and numbered 100, named "Dearborn" or "Ironton"? The evidence indicates this car, if it's the same one, went from DT&I to West Virginia Northern, to MMID, to Chesapeake RR (Eastern Shore), to Aberdeen, Carolina & Western where it now is. 98% chance the same one, but someone's saying it was named "Ironton" and I agree, and don't remember the "Dearborn" name it supposedly left the DT&I with. Assuming we're only dealing with one car, it's a former PRR Z62 business car for superintendents, and was once assigned to and named Williamsport (PA), not to be confused with the ex-Ohio Ry. Museum shell/wreck/skeleton now reportedly at Dennison, OH. A couple other ex-MMID cars are at AC&W, including the PRR twin diner, Pullman Defender, and others. Billy Bartosh's fleet."
I don't recall the "Dearborn" or "Ironton" on the CHRR, only the "Defender" and the "Catoctin." Does anyone have the answer to my friend's question?
